Indiana U. Builds 200‐MeV Sector‐Focused Cyclotron

Indiana University is building a 200‐MeV open‐sector (sector‐focused) cyclotron, which will be the largest of its type in the US. The largest open‐sector cyclotron in the world will be in Zurich, where a 540‐MeV device will be used as a meson factory. The Indiana machine can accelerate other ions to an energy of $240 Q2/M$ (in MeV), where Q is the charge of the ion and M is mass in a.m.u.
